 rimis vestiti, ceteriim dense, graciliter, breviter, pallide puberiili et pinnis 

 reductis, oppositis, remotis muniti. Frondes pinnis reductis exclusis ovato- 

 lanceolatae, usque ad + 75 cm. longae et prope basin ± 2772 cm. latae, 

 acuminatae; racliis dense puberula; pili iis stipitis similes, glanduiis copiosis 

 intermixti. Piiinae firmiter herbaceae, ad et inter costas venasque glanduiis 

 copiosis, partim persistentibus, partim deciduis, subglobosis, flavidis munitae; 

 pinna terininalis lanceolato-subulata vel elongato-lanceolata, infra apicem 

 acuMiinatum subintegerrimumque lobato-deiitata; pinnae latérales + 25 

 utrinque, alternantes, sessiles vel subsessiles, ± remotae, lineares, acuminatae, 

 basi abrupte lateque cuneatae; pinnae superiores ascendentes, parvae, 

 crenatae; pinnae inframediales maximae, ± horizontales, ± 14 cm. longae 

 et IV2 — 1^/4 cm. latae, subintegerrimae ; pinnae infimae + deflexae; pinnae 

 reductae supremae pinnis norinalibus inferioribus subsimiles sed multo 

 minores, sequentes auriculiformes, sensim minores; Costa plus minusve 

 dense, pallide puberula; venae obliquae, usque ad 4—6 utrinque, certe 

 subtus plus minusve parce appresso-puberulae, 3—4 inferiores anastomos- 

 antes. Sori ad venas mediani, usque ad 4 — 5 utroque latere costularum; 

 capsulae paullum setulosae; sporae dense, graciliter, breviter spinulosae; 

 iridusium persistens, brunneum, glandulosiini. 



Resembles very much Versteeg's New Guinean plants determined by 

 Christ as D. multilineata O. Ktze, which, however, hâve the pubescence 

 of the rachis red-brown, and the fronds not glandular. 



Forma typica. — Sumatra (Bengkoelen, Lebong Tandai, C. J. Brooks 

 No. 281/S, January 1917). 



V a r. firmior: Stipites glabrescentes; pinnae coriaceae, maximae 

 serrato-crenaïae :.id -dentatae; basi augustius cuneatae; venae usque ad 

 6 — 8 utrinque, 4 — 5 inferiores anastomosantes — 5wwû/ra {Deli, Haboko,

Var. calvescens, Christ, in Philipp. Journ. Sci., Ile, 193; v. A. 

 V. R., Mal. Ferns, 819: For „axillary setae and pustules" read ..axial setae 

 and pustules." — Spécimens from Java {Megamcndocng, Zippelius Nos. 59, 

 59^7; Mt Tjang Krintjing, Koorders No. 43567 j^:i) have the stipes distinctly 

 setose and pustulose but the rachis nearly or totally naked and smooth.
